Solid Electrolytic Capacitor with Interlayer Crosslinking

摘要

A method for preparing a solid electrolytic capacitor and an improved solid electrolytic capacitor is provided. The method includes providing an anode, forming a dielectric on the anode, forming a cathode on the dielectric and forming subsequent layers on the cathode wherein the cathode and subsequent layers preferably comprise interlayers. At least one interlayer comprises a monomer, oligomer or polymer with multifunctional or multiple reactive groups and an adjacent layer comprises a molecule with crosslinkable functionality. The oligomer or polymer with multifunctional or multiple reactive groups on one layer react with the crosslinkable functionality in the adjacent layer.
